IMPROVEMENT IN PIANO STRINGING AND TUNING DEVICES.

Spzcificatioim forming part of Letters Patent No. 160,600, dated March 9, 1875; application fied November 7, 1874.

.To all whom it may concern:

Be it known that I, WILLIAM F. KEARSING, of the city, county, and State of New York, have invented a new and useful Improvement in Stringing Pianos, of which the following is a specification My invention consists in connecting the strings to stationary rest-pins by a U-shaped device, one leg of which is screw-threaded to receive a nut, and the other is parallel thereto and passing through the rest-pin, thus serving to prevent the device from turning with the adjusting-nut when the tension of the strings is being regulated.

The drawing is a side elevation of a string mounted according to my invention.

A is the string; 13, the screw-threaded leg, and E the parallel leg, of the U-shaped adjnstin g device F. Both legs pass through and slide freely in a stationary rest-pin, O. D is WILLIAM F. KEARSING.
